Selfa SV120M.5.0-330 330W Monocrystalline Solar Panel

Model SV120M.5.0-330 | Monocrystalline | 120 Half-Cell | Mono | 1000V System Voltage

330 Wp

Max Power Output

19.6%

Module Efficiency

120

Monocrystalline Half-Cell

Product Overview

The Selfa SV120M.5.0-330 is a high-quality monocrystalline solar panel built for reliable energy production and long service life. It delivers 330 Wp of rated power with 19.6% module efficiency, making it a strong choice for residential and commercial solar installations. This model uses 120 half-cut cells and advanced module construction to improve output stability and reduce energy loss. It is designed by Selfa GE S.A. in Poland and includes a 12-year product warranty and a 25-year power warranty. With positive power tolerance and durable weather protection, this panel is engineered for dependable performance in demanding environments. Its low degradation rate helps preserve long-term energy yield, which supports better system value over time.

Key Benefits

High Power Output: The panel provides 330 Wp of maximum power for efficient solar generation.

Strong Efficiency: A 19.6% efficiency rating helps maximize usable energy from available roof space.

Long-Term Reliability: The 25-year power warranty supports confidence in long-term system performance.

Low Degradation: A total degradation rate of 0.68% helps maintain output over the product lifetime.

Durable Construction: Tempered anti-reflection glass and IP68 protection improve resilience in outdoor use.

Positive Power Tolerance: The 0 to +1.5% tolerance range supports consistent nameplate performance.

How It Works

This monocrystalline solar panel converts sunlight into electrical power through high-performance photovoltaic cells. The 120 half-cut cell layout helps reduce internal resistance and supports improved energy capture. That structure also lowers power loss under partial shading conditions. The panel operates using a maximum power voltage of 34.7 V and a current of 9.52 A. Those values help define how the module interacts with charge controllers, inverters, and battery systems. Its bypass diode design provides additional protection during uneven light exposure. The tempered glass surface and IP68 junction box help the module perform reliably in outdoor conditions for many years.

Half-Cut Cell Design: The 120-cell structure reduces electrical resistance. It also helps improve output during shading events.

Bypass Diode Protection: Three bypass diodes help limit energy loss across shaded areas. They also support safer and more stable operation.

Weather-Ready Build: Tempered glass, AR coating, and IP68 protection support durability. This helps the panel work consistently outdoors.

Customer Success Stories

Troy P

EG4 off-grid base kit, Happy with my purchase.

This is the first stage of my three planned purches. I got the eg4 inverter 6000 XP base kit with six 400 watt panels and the two server rack batteries. Did a little online research and followed the instructions and it got set up without any issues. Right now I'm just running it in my garage on a single outlet and have been running dual 750 watt water distillers with it. Once I get the second inverter and a bunch more panels and batteries, I plan on attaching it to my subpanel in my house that has my lights and outlets and appliances on it. Then I'll get a soft start for my AC and blower and run it on my main panel.

Jacob B

Easy Process, Genuine Support

Trying to pick the correct solar system for your needs can be very technical and frustrating. I wanted to thank Yvhan and the Portlandia Electric supply team for their patience and helpful attitudes through multiple calls. I feel like we were able to narrow it down to what worked for me and my family. My system works great and I couldn't be happier to have picked Portlandia Electric Supply.

Patrick B

Off Grid Solar Purchase

I wanted to get an offgrid solar system for years but didn’t know where to start. I found Portlandia Electric Supply on Facebook and decided to submit a quote. Within 24 hours I had a custom proposal that was almost half the price of the companies I had previously got quotes from. My wife and I decided to order online and the kit came in a timely manner and it was an easy install. Great company to work with!

James Martin

Highly Recommend

I would like to take the time to express the outstanding service that I was provided with by Portlandia Electric Supply. They provided me with all the answers to my questions, and after reviewing our quote over the phone I felt comfortable proceeding to order my kit. It’s exactly what I needed and they were there to help us over the phone when we had questions installing it. I highly recommend others in need to choose Portlandia Electric Supply.

Solar Kit for Mobile Work Van

As a professional videographer, I needed reliable power on the go.Portlandia Electric Supply Delta Pro and roof-mounted panels were the perfect solution. Setup was easy, and the kit included everything needed. The Delta Pro powers my cameras, lights, laptop, and a small fridge with impressive battery capacity.

Keith S

Best Tech Support

You folks have been wonderful guiding me through the ins and outs of going solar. Plus your tech guys Rod and Nelson are the absolute best. They explained all the different aspects of inverters, batteries and how to keep them in top condition. Too much more to put here… but no other company has the 100% tech support you provide for your customers!

Coll A

Great Experience

My experience with Portlandia Electric Supply has been excellent. Before the sales, they answered all my questions to assure that I got what I needed. After the sales they continued to support me with answers and help. I had a warranty issue with a unit, and it was handled as well as possible. I would recommend them to anyone looking to go solar.
